题
我使用此代码对我的Web服务器执行HttpGet请求。它在模拟器上工作很好,但不是在我的HTC Sense中。Excecution刚刚结束而不进行任何HTTP请求。任何想法?
File f = new File(user.getPhotopath());
List<NameValuePair> reqparams = new LinkedList<NameValuePair>();
reqparams.add(new BasicNameValuePair("email", user.getEmail()));
reqparams.add(new BasicNameValuePair("pwd", user.getPassword()));
reqparams.add(new BasicNameValuePair("name", user.getScreenName()));
reqparams.add(new BasicNameValuePair("photo", f.getName()));
reqparams.add(new BasicNameValuePair("preference", user.getPrefs()));
reqparams.add(new BasicNameValuePair("bluetoothid", bid));
String urlstring = "http://www.mysite.com/me?"+ URLEncodedUtils.format(reqparams, "utf-8");
try {
URL url = new URL(urlstring);
URI myURI = null;
try {
myURI = url.toURI();
} catch (URISyntaxException e) {
e.printStackTrace();
}
HttpClient httpClient = new DefaultHttpClient();
HttpGet getMethod = new HttpGet(myURI);
HttpResponse webServerResponse = null;
HttpEntity httpEntity = null;
try {
webServerResponse = httpClient.execute(getMethod);
httpEntity = webServerResponse.getEntity();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
if (httpEntity != null) {
InputStream instream = httpEntity.getContent();
BufferedReader reader = new BufferedReader( new InputStreamReader(instream));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
resultStr = sb.toString();
instream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
. 解决方案
虽然您的方法是正确的并且将工作,但更容易使用 entityutils 辅助类别将响应体作为字符串检索。简单:
String body = EntityUtils.toString(httpEntity);
. 其他提示
There was no exception nor warning in stacktrace. Only memory allocation messages. Anyway i solved it by using URLConnection instead of HttpClient :
try {
URL url = new URL(urlstring);
URLConnection connection = url.openConnection();
InputStream inputStream = connection.getInputStream();
BufferedInputStream bufferedInput = new BufferedInputStream(inputStream);
// Read the response into a byte array
ByteArrayBuffer byteArray = new ByteArrayBuffer(50);
int current = 0;
while((current = bufferedInput.read()) != -1){
byteArray.append((byte)current);
}
// Construct a String object from the byte array containing the response
resultStr = new String(byteArray.toByteArray());
} catch (Exception e) {
e.printStackTrace();
}
For some reason it worked. Still trying to figure what went wrong.
